Video over IP: Why do it?
Tapes = Going, going, gone
Large content hosting at affordable price
Need to share the same video programming between sites
Video file transfers
IP is the COMPUTER language

Video Over IP: Who’s doing it?
Who is actively buying servers?
Who has video ingress into a server?
Who has recurring content put on a server?
Who has non-real time content?
Answer:
Specialty channels
Centralized broadcasters
Time-zone transmissions
Questions?
